![]() On a mildly modified street car there is only a few hp difference between running an h- or x-pipe with hi-flow cats vs. no cats, though both offer good gains over the choked up stock setup with 6 cats. On a racecar the difference is more noticeable. The main difference is in the sound and emissions legality.
